Network Programming and Administration Using Python
In this course you will learn to
- Learn Python programming skills to write programs that manage and configure network devices
- Write robust code for multi-tasking and multi-threaded operations
- Install and use Paramiko, Netmiko, and NAPALM capabilities for managing and configuring network devices
- Acquire network device information
- Automate changes to network device configurations
Training materials
All Python training students will receive comprehensive courseware.
Suggested attendees
Systems and/or network administrators/engineers/technicians with some experience with fundamental Linux utilities and commands. Python programming experience and working knowledge of a vendor-specific network device (CLI) are useful, but not essential.
